Letters Patent No. 107,611, dated September 20,1870.

IMPROVEMENT IN CHUTES FOR DELIVERING- TIMBER.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern;

Beit known that I, JAMES W. HAINES, of Genoa, in the county of Douglas and State of Nevada, have invented anew and improved Chute for Delivering Timberf'rom High Mountains and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of' this specitication.

Figure 1 represents'a side view of my improved chute.

Figure 2 is an end view of the same.

Similar letters of reference indicate corresponding parts. i

This invention has for its object to furnish to the public an improved chute for facilitating the transportation .of timber of all kinds from the tops or sides of mountains, or other elevations, and consists in constructing a chute so as to present a V-form'in cross-section, the same being arranged on an incline corresponding, more or less, to the surface of the, ground over which it passes, and brought in connection with a spring, Quot-her water-supply, to receive the water therefrom, and thus form a smooth canal throughout its entire length.

Heretofore chutes for this purpose have been constructed with flat, or nearly tlat, bottoms, which, while sniciently objectionable as requiring a greater quantity of water to 'insure equal rapidityin the transit of the timber, are far more so foranother reason, v iz., the log or pice of timber, more especially at points where 'the inclination of the chute is slight, is I liable to be checked in its descent by -friction against the bottom and one side of the chute, and, when thus situated, others may pass it, thus leaving it to be again -set in motion by manual assistance, or other logs striking it; the whole may become wedged together, so as to form a total obstruction to the passage of succeeding logs, destroy the chute at that point', or

cansev other 'serious inj ury, inconvenience, and, in an y.y

A in the drawing represents a wooden trough made of two boards, a and'b, which are joined at an angle of about ninety degrees.'

This. trough is supported by trestlcs or fi'aine'sB B,"

of suitableconstruction, and is built upon the side of a mountain, its upper end being connected with a brook, lake, stream, or spring, to rreceive a supply of running water, which may, if desired, be regulated by I claim as new and desireto secure byLetters Patv 'Thev chute- A, of V-forin,in cross-section, arranged on an incline` in whole or in part, and adapted to receive a flow of water, for the conveyance of timber, as

set forth.`
